The US Supreme Court acknowledged the personal nature and importance of our digital lives today by delivering a unanimous ruling requiring a warrant for cops to search cell phones.

Business Insider reports that the decision, written by Chief Justice John Roberts, says cell phones are a digital record of our most private information and shouldn’t be treated like other items that might be found on a person during an arrest. He wrote, “It is no exaggeration to say that many of the more than 90% of American adults who own a cellphone keep on their person a digital record of nearly every aspect of their lives — from the mundane to the intimate.”

With our digital worlds evolving faster than our laws, this decision is welcome recognition of the need to protect our digital lives and assets.
